EXHAUST-STEAM WATER-H EATER.

SPECIFICATION forming part of Letters-Patent No. 563,84, dated July 14, 1896.

Application tiled March 6 1896. Serial No. 582,040. (No model.)

To all wiz/'0m t may concern:

Be it known that LJMTES STANLEY OAL- KINS, a citizen of the United States, residing at Hastings, in the county of Barry, State of Michigan, have invented a new and useful Exhaustteain IVateeIvIeater, of which the following is a specification.

The object of this invention is to present an increased surface of the water-holding vessels or pans for the hot exhauststeam to come in Contact with, and to construct and arrange said vessels or pans in a way to obtain greater' amount of heat in a given time.

.Another object is to free the exhaust-steam from oil, and to provide an improved means of filtering the water before it goes into the boiler.

Other objects will appear in the following detailed description and elaim.

In the drawings forming a part of this specification, Figure 1 is a side elevation of the apparatus with parts in section on dotted lines a ct and l) b in Figs. 2 and 5; Fig. 2, a Cross-section on line o c in Fig. 1, looking from a point above; Fig. 3, a plan of one of the pans in Fig. l, looking from a point above; Fig. a, a cross-section on line d d in Fig. 1, looking from a point above; and Fig. 5 is a oi'ossseetion on line e e in Fig. 1, looking from a point above.

Referring to the parts of the drawings pointed out by numbers, 5 is a tank, into the upper end of which the water is passed through pipe G, and into the side of which near the lower end the exhaust-steam enters through pipe 7. The water-holding vessels or pans are arranged in the tank 5, one over the other, as many as may be desirable, a small one 8 alternating with a larger one 9. The large ones have a Central hole through them at 10, beneath the small pans 8, as in Fig. 1, for the purpose explained in the operation. The large vessels or pans 9 rest upon supporting-ledges 11. One of the small pans S, the irst one at the top, is sustained on the lower end of the water-pipe 6, while the next three small pans are supported by arms, one 'for each, at 12, attached to and projecting inward .from the door 13. This door is bounded by line 1i in Figs. l and 2, taking about half of the tank in that portion where the pans are located. Vhen the door 13 is opened, the small pans swing out with it on the arms 12.

Just below the bottom large pan is a pendent serrated cone 15, with its smallend pointing downward into the mouth of an oil-pipe 1G. This cone has V-form serrations 19, with the small end of the V downward, as in Figs- 1 and Ll. The top of the eone flanges over at 18, so that all oil which might work up would be stopped by it and run down the serratious and down the pipe 16. 19 may or may not represent a pan, and when it does the liange 18 prevents the water from mixing with the oil by running in the serrations 17.

In the bottom of the tank is a lter 20, and in the lter 20 is a water-box 2l. The lter is filled with some suitable material for the purpose 22, and the side and bottom olosures of the lter are perforated to let the water in through the filtering material 22. The inner walls of the ilter are alittle lower than the water-line. The line e e will serve to show the water-line- The filtering material each side of the water-box 21 is held down by presser-bars 23, held adjustably to plaee by pressure-screws 24, passed through screw-threaded holes in t-he cover to the water-box and filter. This oover 25 is very important and keeps all the filtered water which passes into the waterboX elean.

At 26 is a let-ott and skimmer at the surface of the water and is provided with a pipe to carry off the water when the tank would otherwise get too full. The water should rise just high enough to run over into the waterboX. The skimmer 28 is like a flattened funnel, lying on its side on the water so that any scum which might be on the surface of the water will run into it.

At 30 is a oat having rods attaehed at eaeh side near one end, which rods have bearings in the side wall of the filter 20 at one end and at the other end in the wall of the tank 5. This rod has a crank 3l at the outer end with which is Connected a connecting-rod 32, the upper end of said rod connecting the crank of a valve in the water-pipe G. By this means when the water gets high enough IOO in the tank the Valve will close in the pipe G, and open if the Water getsto'o 10W, and thus regulate the supply of Water.

The Water is drawn from the Water-box by a pipe 84, the end of said pipebeing provided With a screen 35 in the Water-boxin the usual Way. Y

In the operation the Water which comes into the upper small pan 8, through the holes at 36 in the pipe 6, runs said pan over and the Water drips down over the side into the first large pan 9. When this large pan is full enough to run over the flange of the hole 10, it drips down into the next small pan S, and so on, until it reaches the bottom of the tank 5. The steam from the exhaust entering pipe 7 passes up against the broad bottom surface of the large pan and up through the central hole 10 against the bottom surface of the small pan and around it and on up condensing and heating the pans and the Water which it comes into Contact with, and goes on up out of the pipe 3G at the upper end of the tank, if it does not all become condensed before that. The exhauststeam first comes in Contact with the serrated surface of the conev pans or Vessels, the large ones having central hanged holes, and thesinall ones hei'ng supported by arms attached to the door, the Cone serrated oil-colleetor in the path of the incoming steam,- and the covered Water box and filter, substantially as set forth.

In testimony of the foregoing l have hereunto set my hand in the presence of two WitL nesses.

JAMES STANLEY CALKINS.
